Description

Technical Field

[0001] The utility model relates to the technical field of diesel engine protection cooling, in particular to a comprehensive protection cooling device used for the integrated arrangement of gear box protection and peripheral cooling systems. Background Art

[0002] The diesel engine's gearbox protection and cooling of peripheral cooling auxiliary devices (including phase sensors, superchargers with electronic purge valves, urea in the after-treatment system, etc.) are all tasks that must be accomplished by the diesel engine. Limited by the existing diesel engine layout structure, the original gearbox cover can only play a protective role. The original diesel engine's cooling pipes are only used to connect to the radiator, etc., and cannot meet the cooling needs of the peripheral cooling auxiliary devices.

[0003] The existing protective cooling device technology cannot meet the functional requirements of the diesel engine peripheral cooling auxiliary device. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a comprehensive protection and cooling device, in which cooling water channels are arranged on both sides of the box cover of the transmission box, thereby solving the technical problem of integrated arrangement of gear box protection and peripheral cooling system.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A comprehensive protective cooling device comprises a transmission case cover arranged on a transmission case, a first cooling water channel arranged on one side of the transmission case cover, and a second cooling water channel arranged on the other side of the transmission case cover; the first cooling water channel comprises a first water inlet connected to the cooling water channel in the crankcase, a first water outlet connected to the first hollow bolt, and a second water outlet connected to the first plugging cover; the second cooling water channel comprises a second water inlet connected to the cooling water channel in the crankcase, a third water outlet connected to the second hollow bolt, and a fourth water outlet connected to the second plugging cover; after the cooling water flows out of the crankcase, one path enters the first cooling water channel from the first water inlet, and flows out of the two water channels from the first water outlet and the second water outlet; the other path enters the second cooling water channel from the second water inlet, and flows out of the other two water channels from the third water outlet and the fourth water outlet.

[0007] A further improvement of the technical solution of the present utility model is that an observation window for easily observing the situation inside the transmission box is provided on the transmission box cover.

[0008] A further improvement of the technical solution of the present utility model is that: a plurality of bolt holes for bolt fixing are provided on the transmission box cover.

[0009] A further improvement of the technical solution of the present utility model is that the first water outlet and the third water outlet are both horizontal outlets.

[0010] A further improvement of the technical solution of the present utility model is that the second water outlet and the fourth water outlet are both downwardly inclined water outlets.

[0011] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is:

[0012] The utility model provides cooling water channels on both sides of the special-shaped case cover of the transmission case. After the cooling water flows out of the crankcase, one path enters the first cooling water channel from the first inlet and flows out of the two water channels from the first outlet and the second outlet; the other path enters the second cooling water channel from the second inlet and flows out of the other two water channels from the third outlet and the fourth outlet. The outflowing four water channels can be used to cool peripheral auxiliary devices, so that the comprehensive protective cooling device can not only realize the protection of the transmission case by the transmission case cover, but also realize the cooling of peripheral cooling auxiliary devices (including a phase sensor, a supercharger with an electronic purge valve, a urea tank assembly in the after-treatment system, etc.).

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0024] like Figure 1-5 As shown, a comprehensive protective cooling device includes a transmission case cover 3 arranged on the transmission case, a first cooling water channel 1 arranged on one side of the transmission case cover 3, and a second cooling water channel 2 arranged on the other side of the transmission case cover 3; the first cooling water channel 1 includes a first water inlet 1-3 connected to the cooling water channel in the crankcase, a first water outlet 1-1 connected to the first hollow bolt 4, and a second water outlet 1-2 connected to the first blocking cover 5; the second cooling water channel 2 includes a second water inlet 2-3 connected to the cooling water channel in the crankcase, a third water outlet 2-1 connected to the second hollow bolt 7, and a fourth water outlet 2-2 connected to the second blocking cover 6.

[0025] Furthermore, the transmission case cover 3 is provided with an observation window 3-1 for convenient observation of the transmission case interior. Because two cooling water channels are provided on either side of the transmission case cover 3, which need to be connected to other cooling pipes, the transmission case cover 3 is not easy to remove after installation. Therefore, the inspection window 3-1 is provided on the transmission case cover 3 to facilitate observation of the transmission case interior.

[0026] Furthermore, the transmission box cover 3 is provided with a plurality of bolt holes for bolt fixing.

[0027] Furthermore, the first water outlet 1-1 and the third water outlet 2-1 are both horizontal outlets.

[0028] Furthermore, the second water outlet 1-2 and the fourth water outlet 2-2 are both downwardly inclined water outlets.

[0029] Note: Because the openings of the first water outlet 1-1 and the third water outlet 2-1 are horizontal, the first hollow bolt 4 and the second hollow bolt 7 are provided for the convenience of connecting other cooling pipes. Direct connection is sufficient. Because the openings of the second water outlet 1-2 and the fourth water outlet 2-2 are tilted downward, the first and second plugging covers 5 and 6 are provided for the convenience of installing the transmission case cover 3. When other cooling pipes need to be connected, the first and second plugging covers 5 and 6 can be removed to connect the other cooling pipes.

[0030] like Figure 3 As shown, the outer edge contour of the bottom of the transmission case cover 3 is consistent with the outer edge contour of the transmission case (special shape), and is sealed with the crankcase by a special-shaped sealing gasket, so that the oil splashed from the transmission mechanism gears is sealed in the transmission case, and at the same time isolated from the first cooling water channel 1 and the second cooling water channel 2.

[0031] like Figure 4 As shown, the arrows on both sides of the figure indicate the two water channels (first water outlet 1-1, second water outlet 1-2, third water outlet 2-1, fourth water outlet 2-2) flowing out of the left and right water channels (first cooling water channel 1 and second cooling water channel 2), respectively, which can be used to cool the phase sensor, the supercharger with an electronic purge valve, and the urea tank assembly in the after-treatment system.

[0032] like Figure 5 As shown, the arrows on both sides of the figure indicate that after the cooling water flows out of the crankcase, one path enters the first cooling water channel 1 from the first water inlet 1-3, and flows out of two water channels from the first water outlet 1-1 and the second water outlet 1-2; the other path enters the second cooling water channel 2 from the second water inlet 2-3, and flows out of another two water channels from the third water outlet 2-1 and the fourth water outlet 2-2.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
